Silicon nitride sintered body |
摘要 |
A silicon nitride sintered body includes silicon nitride as a principal component, silicon carbide dispersed therein and at least one of boron and boron compounds in an amount of from 0.005 to 0.5% by weight in terms of the weight of boron with respect to the total weight of the sintered body. The addition of boron or boron compounds improves the high-temperature characteristics such as creep resistance of the sintered body.
